i TOV ALL WHOM IT MAY CONCERNE Be it known that I, JOHN' W. POST, ofCastile, in the county of Wyoming, and State of New York,rh'ave molde anew and useful Improvement in Skates; ,and Ido hereby declare thefollowing to be a full and correct: description of the same, suicient toenable others skilled in the art to which my invention appertains tofully understehd and use the same,rei`ercnce being had to theaecompenying drawings, melting part of this specifica non, and in which-Figure 1` is a bottom view of my iniproved skcte. Figure 2 is asectional side elevation .of the same; and

Figures 3, 4, and 5, are-detached views of parts of the same.

ASimilar letters of reference indicate corresponding parts in theseveral figures.

A, in the drawings, represents the runner attached to the standards Cand D of the foot-plate B, by rivets c and d, its front end passingintothe foot-plete, as shown at a. 0n the standard C is formed .theheel-ping b, which ts intoa hole made in the heel oi' the boot. e is a.L-shaped spring-lever, one ntin Of which is-providcd witl' a knob, e',and the other with olholel fitting over a projection, f, which forms thepivot of the lever e'. This 'lever e is. secured to a bar, E, by meansOils. rivet,g, in such a, manner that the lever `e may move on therivet, The rear ,Y end of the har EA is providednithe sharp point, andthe under side of the front end is serrated, and provided i with a. holein which is formed a female-screw thread, and rests Onthe serratedsurface of the slotted rear Aend i of the har F, to which it is securedby means of a screw, h, passing upwards through the slot z' in the barF, l and into the hole in the front end of the bar E. AThe bar E is madewider in that pnrt which passes over the l arms jj of thestandard D, soas to form e biete, k, which is. provided at its under side with two`ridges Z, thc l forward ends of which are inclined towards each other,and 'dt in' diagonal grooves inthe horizontal 'parts of l the clamps G.It will be easily understood that the clamps Gr are forced outward bythe ridges l l working in the grooves m, when the har F is movedforward, and drawn toward eachother when the bar F is moved backward,which isdone by means of the-"lever liveted to the bar E, whichis'afgain connected to the bar F, as already described, and asthe bar Fis provided with n slot, z', `which allows the liars 'E and F to overlapeach other more or less, the distance between the clamps Gcan'becasly'regulnted to suit each particular foot, byA merely'looseningthe .screw h, moving the bar F forward or backward, as thel case may be,'and again securing a, 'rigid connection between the bars E and F bytightening the screw h; the serrated under side of the forward end ofthe har E, and serrated surface of the rear end of the bar F 'preventingany slipping.V The cross-piece H of the front pla-te I3 hes depression,o, into which thespringdcver e tits when theske'te is fastened to theIj'oot, and prevents the lever from loosening'accidentally. Theblacklinesing. 1 indicate the positionofthe bars E and F and level-"e,when the skate is loosened 'from the boot, the hars beingpushed forwardVby the pivoted spring-lever @,which withdraws the pointed end of thebarE from the inner side of the heel, and frces the clamps G outwardly.In rod linestheir positionis shown when the skate is secured to thefoot, .the levere `resting inthe depressione, the point of the bur E inthe inner end of the boot-heel, and the clamps G drawn towards eachother by means of'the moving back of the bars and E. n is n projectionwhich prevents the lever e from being moved over on that side. Thisskate contains but three rivets, c, d, and g, and one screw, la, alllthcother parts beinglcast or cutout from' metal. Its'mode of adjustment tothe bootis simple, a'nd theskate can be quickly 'and firmly secured tothe same;

Having thus described my invention, what I claim as new, und desire tosecure by Letters Patent, is. 1. Adjusting the clamps G by mea-ns of theserrated bar F, provided with 'a slot, z'fin combination with theserrated forward end of the vhar E, both held in position' by a. screw,L, substantially as descrihed.

2. The device for fastening the skate to the boot,ilconsisting of theL-shaped spring-lever e,'rivcted to b nr E, with serrated and slottedrear end, and ridges Z, fitting into slots mon the clampsG,substantially aimeseriheLi-lY To 'the above I have signed myname,thislth clay of July, 1867'.
